Abstract
Abstract A hand held tool 211 for inserting or removing a fiber optic contact alignment tube segment 47 into a fiber optic connector 13. The tool includes a hollow shaft 215 anchored in a knob 213 and extending coaxially through a cylindrical chamber in the knob. A core 225 having an axial bore extending therethrough resides rotatably in the chamber, with the post acting as its shaft. A shroud 235 extends from the core 225 and has an arcuate slot 237 near its tip. When an alignment tube segment 47 is inserted in the hollow post 221 and the shaft 215 is turned 180° relative to the core 225, an enlarged portion 48-2 of the base of the tube segment 47 enters into and is captured by the slot 237. The tool may then be inserted into a connector whose front end mirrors the front end of the tool 211. When the knob 213 is again turned 180°, the tube segment 47 is turned inside the connector causing its enlarged base portion 48-2 to enter a slot similar to the slot 237, thereby capturing the tube segment in the connector, after which the tool may be withdrawn.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
118 words
A tool for inserting or removing a tubular member having an asymmetrically configured baseplate into another member having a slotted receptacle for receiving and retaining said baseplate comprising in combination: (a) a hollow shaft or post for receiving said tubular member up to, but not including, its baseplate; (b) a core mounted coaxially with and rotatable relative to said shaft; (c) a shroud extending from said core beyond the tip of said shaft and partially surrounding said shaft; and (d) a slot in the end of said shroud lying in a plane orthogonal to the axis of said post or shaft for receiving the baseplate of said tubular member when said core is turned relative to said shaft.
Claim 2
Dependent Claim
118 words
A tool for inserting or removing a tubular member having an asymmetrically configured baseplate into another member having a slotted receptacle for receiving and retaining said baseplate comprising in combination: (a) a hollow shaft or post for receiving said tubular member up to, but not including, its baseplate; (b) a core mounted coaxially with and rotatable relative to said shaft; (c) a shroud extending from said core beyond the tip of said shaft and partially surrounding said shaft; and (d) a slot in the end of said shroud lying in a plane orthogonal to the axis of said post or shaft for receiving the baseplate of said tubular member when said core is turned relative to said shaft.
Claim 3
Dependent Claim
58 words
The tool of claim 1 characterized further in that: (a) said core has an axial bore extending therethrough; (b) said post or shaft extends through said bore to permit rotation of said core upon said post as its shaft; and in that (c) said tool additionally includes means to restrain axial movement of said core upon said shaft.
Claim 4
Dependent Claim
36 words
The tool of claim 2 characterized further in that said shroud is configured to interfit with an alignment post extending from said other member into which said tubular member is to be installed by said tool.
Claim 5
Dependent Claim
51 words
The tool of claim 3 characterized further in that said core additionally includes an alignment post extending from said core diametrically opposite said shroud and configured to interfit with an alignment shroud extending from said other member and having the same contour as the alignment shroud which extends from said bore.
Claim 6
Dependent Claim
49 words
The tool of claim 2 characterized further in that: (a) said tool additionally includes a knob having a chamber terminating in an end wall; (b) said post is anchored in said end wall and extends through said chamber; and (c) said core fits into said chamber for rotation therein.
Claim 7
Dependent Claim
33 words
The tool of claim 1 characterized further by a plurality of pins mounted on the rim of said hollow shaft for keying engagement with a corresponding plurality of index holes in said baseplate.
Claim 8
Dependent Claim
67 words
The tool of claim 5 characterized further by: (a) keying means on said shaft to rotationally locate said tubular member on said shaft; and (b) means on said core for providing a pair of stop positions for said core, said stop positions located to register respectively with the positions in which the base of said tubular member is within and outside of the slot in said shroud.
Claim 9
Dependent Claim
64 words
The tool of claim 7 characterized further in that said plurality of pins comprise a pair of pins mounted 180° apart on the rim of said hollow shaft and in that said means for providing a pair of stop positions includes a groove running around the periphery of said core and a pair of recesses located 180° apart in a wall of said groove.
